Cascade systems with C02 - a promising trend in refrigeration technology (York)


Currently, the main refrigerant used in large industrial refrigeration plants is ammonia. This is due to its excellent thermodynamic properties and environmental friendliness. At the same time, many big refrigeration facilities are located in the densely populated regions, which is not safe for the population in case of emergency emission of ammonia. Various technical solutions are currently used for localization and reduction of emissions.

Danfoss Maneurop hermetic compressors


In 2001, the Danfoss Maneurop compressor technical expertise center (KM) was established in Moscow. Based on the data accumulated during its work, statistics were compiled and an analysis of the causes of KM failures was carried out. The overview of the causes of KM failures given in the article will help to avoid mistakes in installation and operation and reduce the risk of abnormal situations. Presented cases are common not only for Danfoss Maneurop KM, but also for other hermetic KM, except for those, which are connected with design features of this or that model.

Installation of refrigerating machines with hermetic compressors with cooling capacity from 200 W to 4 kW


The installer is often limited in the choice of location for the components of the refrigeration machine: the location of the refrigerated volume is already given, and it vists the location of the compressor (unit), start-up and protection devices of electric drives and determines the routing of pipelines. Nevertheless, for efficient operation of the walking equipment, as well as for safety, it is necessary to strive for fulfillment of a number of requirements to the machine room.
